how to load kernel drivers in target board(imx6qp-sdb)

[vasusriram]

Hi everyone,

I am using yocto tool chain build linux images(.sdcard image) o imx6qp.

i followed process as they mentioned in the document as follows

    -> mkdir bin

    -> curl https://storage.googleapis.com/git-repo-downloads/repo > bin/repo
    
    -> chmod a+x bin/repo

> export PATH=bin:$PATH

Download the i.MX Yocto Project Community BSP recipe layers:
 
    -> To download perform the following steps:

    -> mkdir imx-yocto-bsp
    
    -> cd imx-yocto-bsp

    -> repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-rocko -m imx-4.9.88-2.0.0_ga.xml

    -> repo sync

    $ DISTRO=fsl-imx-xwayland MACHINE=imx6qpsabresd source fsl-setup-release.sh -b build-xwayland

    $ bitbake core-image-minimal

$ bunzip2 -dk -f <image_name>.sdcard.bz2

    $ sudo dd if=<image name>.sdcard of=/dev/sd<partition> bs=1M conv=fsync

--------------------------------------------------------------------------------------------------------------

upto know its fine and its loaded perfectly and login with root

Now the problem is i was trying to load the kernel modules

it is showing error like follows

modprobe: FATAL: Module "module_name" not found in directory /lib/modules/4.9.88-imx_4.9.88_2.0.0_ga+g5e23f9d

how to load drivers into my target and how to interface with them plz help.

Thanks in advance.

Hello Ram,

The process you are following is correct. However, it seems that the modules you are looking for are not available on the core-image-minimal recipe. Would you please review if that’s the case? You do not mention which modules you are looking for but perhaps it’s not part of the core-image-recipe.

I hope this helps!

hello gusarambula,

I am checking for the acclerometer(mma8451) module. when i try to load that module it is sowing that as already registered.but i wasn't showing in drivers/hwmon folder in board kernel.
